These are newspapers and are there to stay permanently don't ever delete anything in them .
Nabble's policy is to delete content that is not accessed for a prolonged period.
Administrators are warned of content that is about to be deleted and told of the action that must be taken to ensure it is not caught by the automated process. Authors are sent copies of deleted material, so they can re-post if desired.
Once deleted, content is removed from Nabble's database and cannot be restored by them. It is down to the forum administrator to ensure all content to be retained is kept active.
I guess it is possible that if you pay for Premium Support, you could request a change to that routine for your forums, but you'll need confirmation from one of the Nabble team for that.
Volunteer Helper - but recommending that users move off the platform!
Once the admin for GregHelp now deleted.
